Bottom trawling destroys ancient shipwrecks with zero tracking

Commercial bottom trawling drags heavy nets and metal doors across the sea floor, physically destroying wooden shipwreck structures, displacing artifacts, mixing sediment layers that provide dating context, and altering the chemical environment that preserved organic materials for centuries. A study of 45 shipwrecks in the Aegean and Black Seas found trawling damage on the majority of accessible sites. Unlike terrestrial archaeological sites, which at least have some legal protection framework, most underwater cultural heritage in international waters has no enforceable protection at all. The real pain: shipwrecks are time capsules that preserve organic materials (wood, textiles, food) that rarely survive on land, making them uniquely valuable for understanding ancient daily life, trade routes, and shipbuilding technology. Once trawled, this evidence is scattered or destroyed permanently. The structural cause: the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage has not been ratified by major maritime nations including the US, UK, and Russia, fisheries regulators do not consider archaeological sites in trawling permits, and there is no comprehensive inventory of wreck locations to even establish exclusion zones.
